Frequently Asked Questions

Everything you need to know about Tide Alert: Tide Chart & Wind's features and capabilities.

How accurate are the tide predictions?

Where an official hydrographic agency publishes predictions, Tide Alert uses that data directly — including the UK Hydrographic Office (UKHO) in the UK. For coastlines outside the agency networks, a global tide model delivers high and low tide predictions, extending accurate coverage to 128 countries.

Which countries does Tide Alert cover?

Tide Alert covers coastlines in 128 countries. Official agency data is used where available and a global tide model fills in the rest, so you can get high and low tide predictions for virtually any shore on Earth.

Does Tide Alert show moon phases?

Yes. Tide Alert includes a moon calendar with the current moon phase, moonrise and moonset, sunrise and sunset times, and solunar major and minor periods — so you can plan around the moon as well as the tide.

Do I need internet connection to use the app?

Once downloaded, tide data is cached locally. You can view tide charts and predictions offline, which is ideal for coastal walks and sailing. Real-time weather and swell data requires an internet connection.

Can I set custom tide level alerts?

Yes! Set notifications for high tide, low tide, or any custom tide level. Perfect for boat access, fishing spots, or beach safety planning.

Does the app work on Apple Watch?

Yes, Tide Alert includes full Apple Watch support with complications, widgets, and Siri integration showing current tide status and next tide time.

Is this app good for fishing?

Absolutely! Includes moon phases, solunar periods, sunrise/sunset times, and tide patterns that help determine optimal fishing times, wherever you fish.

Does it show wind and water temperature?

Yes, wind, air temperature, water temperature and swell forecasts are available for a 10 day period.

Is Tide Alert good for surfing?

Yes! Surfers use Tide Alert to track optimal tide conditions, swell forecasts, and wind data. View 10-day swell predictions with wave height, period, and direction.

Do I need separate subscription for iPad and iPhone?

Absolutely not. Your subscription will cover all your Apple devices including iPhone, iPad, Apple Watch and Mac.

Does slack water always occur at high and low tide?

No, this is a common misconception. According to NOAA, the relationship between high/low tides and slack water depends on local conditions. In some locations (standing wave), slack water aligns with high/low tide, but in others (progressive wave), maximum current occurs at high/low tide instead. Learn more in our detailed guide on slack tides.
